Radicalism and Music offers a convincing argument for music's transformational impact on the radicalization, reinforcement, and motivational techniques of violent political activists. It makes a case for the careful examination of music's roles in radical cultures, roles that have serious impacts, as evidenced by the actions of the Frankfurt Airport shooter Arid Uka, Sikh Temple murderer Wade Page, white supremacist Matthew Hale, and animal-rights activist Walter Bond, among others. Such cases bring up difficult questions about how those involved in radical groups can be stirred to feel or act under the influence of music.
Radicalism and Music is based on interviews, email correspondence, concerts, and videos. As a "sound strategy," music is exploited to its fullest potential as a tool for recruiting and retaining members by members of al-Qa'ida, the Hammerskin Nation, Christian Identity, Kids in Ministry International, Earth First!, and Vegan Straight Edge. But, as the book points out, the coercive use of music is not isolated to radical cultures, but in political propaganda, sporting events, and popular music as well. Ultimately, Radicalism and Music shows how music affects us through our emotions, and how it triggers violence and enables hateful ideology.
